Well, first 750pts touney is under my belt... I entered with first list in this post (one with 2 typhoons)... It was interesting, less competitive than I thought , so I managed to end 5th (out of 11)... Had some trouble with luck and so on...
What I didn't know, the special rule was not 1 ELITE,
FA and
HS.... It was 1 ELITE or
FA or
HS 
(thx god I just had fast attack)
Anyways, there were lots of orks (3/11) and most were built same way (40 boyz and trukk with nobz and warboss), few space marines (mostly chaos, space wolfs, ultramarines) and one of nidz and eldar...
Here is my battle report:
GAME 1: SPACE MARINES vs NIDZ
MISSION:
Capture and control
DEPLOYMENT:
Dawn of war
OPPONENT LIST:
Tyranid prime + 5 warriors
3x Hive guard
11x Genestealers
Well, this was easiest game ever... Must say, opponent didn't have much experience (he said that he used to play a while ago, but hasn't played in a long while), I knew his dex and stats of each unit better than him...
I have won the roll-off, and had let him go first... He has put everything (except guards) as close as possible to me... To make things short, I have flamed the hell out of genestealers, and used my 6 rokkits per turn to take out his warriors (best way to get rid of T4 3W monsters is to shoot at them with S8

) and engaged survivors with one of my tactical squads... Then I have shoot down as much as missiles as possible at hive guards and sent one rhino at him... After losing 1 guard and having one more wounded, I have engaged them and killed them i
cc... In this game, I didn't lose a single model
Wiped him off board in turn 4 and this were my first 20pts...
GAME 2: SPACE MARINES vs ORKS
MISSION:
Annihilation
DEPLOYMENT:
Pitched battle
OPPONENT LIST:
Warboss + 9 nobz (eavy armour, big choppa, waagh banner, painboy) + trukk(some upgrades, like
rpj and that thing for dangerous terrain reroll)
2x20 boyz boyz boyz
Well this game was a disaster... I won the roll off, and started first...
TURN 1:
Moved typhoons so that I can fire them at his trukk... We had an argument here, as I could only trace
LOS from one of my typhoon launchers, so he said that I can fire only one shoot... I tried to reason with him as typhoon is a single weapon that has two shoots and it's enough to trace
los from one launcher to be able to shoot those 2 shoots... He was persistent so we agreed to roll off to se who's right...č He won (

)... Then he said that my landspeeder blocked
los of the other landspeeder, and I have tried to convince him that it doesn't matter as they are same squad... Had to look up at
brb and show him, and then call
TO and ask him to put some sense into that dude (he already damaged me for 2 shots, would not give 1 more)... Finally, the
TO said I was right.... Took my 2 shoots at his trukk, hit both and didn't penetrate

...
He moved towards me with boyz (they were slow as he has put them into cover from my launchers) and moved trukk into area terrain...
TURN 2:
Another argument... I had 6 rokkits shooting at him at his trukk, that laid in area terrain... He insisted that he had 4+ cover, and I tried to reason with him (again) that he can get his 4+ save ONLY if 50% of trukk is obscured... He said that when he attended
GT, everyone have played that way, and that he should have his 4+ save... We argued about it a bit, and as I didn't want to spoil game (I went there just for fun, not to be winner at all cost) I have allowed his 4+ save... 6 rokkits, 3 hits, 2 penetratings, 1 save and weapon destroyed
His turn... He moved nobz and multiple assaulted my rhino and one squad of marines... Got 2 killpts and consolidated into my wrecked rhino... Boyz still advancing and at my doorstep...
TURN 3:
I moved typhoons away and blasted 4 rokkits at his nobz... Killed only one... Moved marines and other rhino (with librarian) towards first boyz squad (second got stuck away, so they couldn't charge next turn)... I have flamed them and shot them with pistols, and avengered with libby + flamed with other squad... There was nob + 4 boyz left... I charged them with my 10 marines... Killed only 2 boyz in 18 normal attacks + 3 power fist attacks!!!!! He has killed 4 of my marines...
His turn... He moves his nobz out of wrecked rhino, and gets 6 on move through difficult terrain (
ofc), waaghs and manages to assault my marines and double assaulted my other rhino with only warboss... Had 2 more marines standing and dead rhino (hehe

)... At the end of this turn, I had 0 kill pts, and he had 3, plus one squad almost dead.......
TURN 4:
I knew that there is no way out of it, so I moved my typhoons 24'' to get away from orks (didn't want to be wiped out, as I would get 0 pts, so I decided to try to survive for that 3pts that I will get)... Assaulted him with libby and 5-men tacs... Tried to pull force weapon on his warboss, but I didn't wound him... Still had few tacs left in combat that turn
His turn, he moved his orks and run towards my survivors, ignoring landspeeders...
TURN 5:
Blown off his trukk (finally) with speeders from other side of the map... At that point I have asked him if he wants to wrap up the game and claim 17pts, as there is no way he can catch my speeders... He agreed...
So at the end of this game, I had 23pts + 11 pts for painting (out of 15; I didn't flock the bases of models)... Total of 34pts...
GAME 1: SPACE MARINES vs CHAOS SPACE MARINES
MISSION:
Sieze the ground
DEPLOYMENT:
spearhead
OPPONENT LIST:
Chaos lord w
PF and plasma pistol
9x khorne berz. (one with fist and plasma pistol)+rhino
5x havocs (4
ml)
5x Plague marines
He won the roll-of and went first... There were 3 pts, one on the middle, one in opposite quarter (left of him) and one in my quarter... He has put plagues as close as possible to the point, havoce on higher terrain near second point and rhino as close to me as possible... I have cobat-squaded and put my
ML squads in ONLY terrain there was on my side (near my table edge), put rhinos so that one without libby protects one with libby from
ml and typhoons close tho his side behind the cover...
TURN 1:
He decided to shoot down my typhoons... All he managed to do was to shake one... Moved rhino and poped up smoke... Nurgels moved into terrain where objective was...
My turn, moved rhinos 12'' towards his, and fired 4 rokkits at his rhino... Weapon destroyed

... Popped up smoke...
TURN 2:
Made a mistake... Didn't know that his nurgels had plasmaguns... Me moved and declared rapid fire and was exactly in 12'' (darn

)... Lost one speeder... Rokkits took out second... Moved his rhino out of
los of my rokkits...
My turn, fired rokkits, 4 rapid fire bolters and 2 storm bolters at havocs... Killed 3 havocs...
TURN 3:
He saw that there he is losing this way and that he has to get out with berzerkers... He multi-assaulted my rhinos and both exploded... He lost 2 berzerkers in explosion... I lost 5 marines
My turn... Got him right were I wanted him... Had 2 flamers at him and libby with avenger... And then, epic fail! Failed leadership test for libby!!!!! Still, took out lots of berzerkers with shooting pistols and 2 flamers... Charged into them... Again epic fail... One sarge was forced to attack last berzerker, and managed to hit all attacks with
pf and wound all (that is 3
PF wounds on single berzerker)... 3
PF attacks missed his chaos lord!!! His 7
PF attacks (one berzerker that i killed at I1 and lord) all 7 hit and wound... Lost combat, failed leadership and managed to run from combat
TURN 4:
His lone lord walks behind rhino as rhino is advancing towards my point... To make things short, couldn't pop his rhino with
mls... He has hit me with havocs and killed my
ml (had to put all tacs pretty close, as terrain was terrible, and he had put blas over me, having all 5, making all 5 wounds, and only wound that I have failed was one allocated on
ml 
)... Rhino contested my point and game ended... He had won by having 1 point and I had 0.... That was another 3 pts for me...
So all in all, it was fun... Had terrible luck (as always) but still every game was interesting... Next time I intend to complete my space wolfs and go with 4 vehicles (hehe

)....
Any advice on gameplay? Any mistakes I made (except obvious ones)... I am aware that opponents didn't play too good (most of them) and have made lots of mistaks, which I tried to make into my advantages as much as possible... Any suggestions about target priorities that I (or my opponent) didn't play out well? Like to have some critics, as I am (kinda) new player (I have lots of games under my belt but just with friends, so ork, eldar and necrons are my specialty

)....
