If calculation is needed, I can think 2 to 4 moves ahead ..... sometimes I don't calculate. I just see the position, then play what I think is the best move.
how many moves you think ahead

The quality of the moves you think ahead is what's important, not so much the quantity. I would rather see 4 good moves per branch of calculation than 14 mediocre moves.

often loses me the game, too. drat.
Stop telling porky pies. There are naive people on here that will believe you, try to do the same, and waste their time when they could be improving their chess.
