Nos 1 game, instead of 5.d5 you could have done Bb5 11.Qd3 what about f4 !? that would have be good for your bishop if PxP and open the f-file for your rook.
A tournament
Sort:
Game 2. 10.Rd1 10.Nc3 to free your other rook. You played well here, black was ahead untill 37...Kxf4 ?? should have focus on his a b c pawns, yes time pressure really put you off. On the analysis engine (you have one ?) it keep screaming at me for you to go Re2 during the second halve of the game, does yours say that too ?
Game 3. found something interesting instead of 15.Qxc6 first do Bh7+ Kf8 now then Qxc6 the bishop is safe on h7. 27.Rc5 ? Rcxc7 ! is better
Here is a tournament I played in, some of the games are less interesting than others. Game 2 and 4 are most interesting.
