There are 2 styles:
1. Always be the one with initiative, don't play defensive moves. Don't react to opponent threats, be agressive and quick and create a mess and attack.
2. Ruin opponents play. When they move, see his plan, usually are 1 move attacks or its pretty obvious and make sure you stay solid and corrupt his attack. Play the opening and then just wait for blunders etc. Don't hang pieces. 1700 don't know what they are doing most of the time and still blunders pieces specially if you have knights at the endgame. They are more valuable than bishops in bullet.
Learn basic rook endgames. Always be with active king and rook. You can flag 2000 rated players if you have rook at endgame and know how to use it. Many 1700 elo players are terrible at endgame. Talking about players with max elo 1700
I would recomment to have enough fun with bullet and quit it after few thousand games. Its really addictive and after that point it does not improve you anymore.
1750! I hope this little spike goes to 1800 haha
