janr: if black pincers, white risks to have to take the territory in the corner (good!) but also to give black influence which works well with the marked high black stones.

Therefore, I would prefer to play at A on the start point.  This works well with the white shilari in the top left.]

Would it make sense to start with a reducing move around A?

;B[mn]TR[nc][qf][qk][gm][nm]C[what to do now to struggle against black's moyo ???

(LL)

janr: while black's moyo grows larger, it gets more difficult to reduce.  Still, an invasion may be possible due to the few weaknesses it has.  see variation]

;B[qf];W[jd];B[nl];W[qh]LB[ne:B][ik:A]C[

janr: the largest black territory is in the center.  Attacking this white stone may significantly increase the center.  How about (A) reducing of (B) building the white territory on the top?]

(LL)

Janr: The A-B combination of stones is know to attack well the C-D pattern of stones.  
It seems not a good idea to bump against black and strengthen him.  If you want to attach, I would prefer the leaning attack on the other side, e.g. at E.]
