Post subject: Peep and extend question

I was facing a friend yesterday and he played a shape twice which I'm not sure I responded optimally to either time. I ended up winning both games presented here, but I'd like some answers on how I could have handled those situations better. The outside shapes are quite different, so I'll present both games separately.

Both games are two-stone handicap games and I played white.

Game 1

This was the situation when he peeped.

Was

correct? How could I have handled his :b6:

better? Or is the way I played good enough?

Game 2

This is where we were when he peeped. Once again, I connected solidly, and one again, he tried to pull out into the side.

Because this variation is a lot longer, I've included an sgf of how the game went from here. I think :w49:

was too early and :w51:

should have been at R3, but I'm also curious how you would play in this situation, and if my move at :w71:

was effective enough.

Thanks for any help you can give me with these situations!

In the first game, 1 seems best as you played it. I would have played 3 at 6 ( or maybe 010 )

In game 2, again your reply to the peep seems best. I would have played 4 thus:

answering the peep is the best move for both.

I would also connect like that. But the game result somehow feels a little unfortunate for white, I think. How about this (just an idea):

Post subject:	Re: Peep and extend question
Almost every time I play something other than the solid connection in that position vs. a stronger player it turns out very badly for me. Also I've noticed that if I'm the one playing the peep against a weaker player, they get into a lot of trouble if they don't connect. I think you did fine, although I'm not sure how you won the first one...
